RANGE JET BURNER.

Application filed November 13, 1923. Serial No. 674,477;

This invention concernsheating apparatus in which liquid fuel is used,and in particular, types adapted fordomestlc purposes.

The invention has as one of'its objects to casing.

there consumed in such manner as to dis-.

tribute the flame and heat in an adv-antageous manner.

Other ob ects are, to provide an initial igniting device adapted forcleanliness, econr vonly and safety, and particularly for induc-- ing anair draft whereby atmospheric air 1s mixed with the flame and deliveredin such manner as to rapidly raise the gas generating or expansionchamber and .burner to such temperature as may be required .to convertoil entering therein into a gaseous condition.

Still another object is the provision of a plurality of deflectingplates on a single friction collar so that when one deflecting plate ispresented to the flame,the other mothers will be away from the flame tobe readily cleaned of soot or other accumulations of w carbon.

. The several object's'are secured by the 40.

novel arrangement of specifically formed parts, as later describedandillustrated in the appended drawing, in which I Figure 1 is afragmentary plan view of a multiple burner apparatus made in conformitywith the invention, parts being'in horizontal section on the line m-wofFig. 3. Figure 2 is a partial transverse sectional view taken onplanecorresponding to line 2-2 of Fig. 1, but showing a slightmodificontinuous to one end of each recess and is held therein by thelock nut 25 and fixedin cation. I

Figure 3 is another sectional view taken in a plane at a right angle toFig. 2 on line 3 3 of Fig. 1 but showing a modification of the deflectorplate arrangement.

Figure 4: is a side view of a further modification of the deflectorplate arrangement.

Figure 5 is a top view and Figure 6, a'side view of another form ofdeflector plate unit. Figures 7 '8 and 9 are side views of still otherforms of'deflector units.

In Figure 1 appears one end of a generally flat topped support framearranged to receive one or more pairs of burners one of WlllCll, at theleft, being a plan and the other on the right, being asection asindicated by the line of Figure 3.

i The support frame, preferably a metal casing, is generallyrectangular, although its contour may be fancifully made in anypreferred shape, its upper surface 10 being essentially level havingopenings 11 to lighten its weight and permit ,of'f-ree air circulation.

The outwardly beveled marginal walls'12 terminate in lbeadededges 13suited to rest upon any convenient level surface and contam openings 14correspond ngin purpose with the openings 11.

Below each burner an 'oblong rectangular depression is formed'in the.frame, its Walls 15 flaring slightly inward to the flat, level bottom16, from which risevertic'al walls 17 joined ,by'a cap-18 raised toapproximately two thirds of the distance from the bottom 16 to the frametop 10. I w

l Said cap 18 and also in the modified form,

thesidewall 17, contain perforations 19 allowing air from below theframe to-enter the channelled recess 20, interjacent the walls 15 and17, this recess having disposed in it a quantityof non-inflammablefiber, as asbestos, to act as a Wick 21,;tl1e channel constituting afire box as will later be seen, and centrally on the cap 18'is a rib 22raised above r thesurfaceof the frame 10, asbest seen in Figures 2 and3. I v V Formed with the side walls'15 are raised and outwardly curvedwings .or guards 23,

highest at their centers and adapted to direct liquids into therecesses;,and extending between adjacent recesses are grooves 24 forcollecting excess liquid on the surface of the frame,-directing the sameinto the recesses.

An independent liquid fuel supply pipe 25 leads to a raised boss 26formed on the frame the boss is a tube 27 bent at a right angle toextend over the perforate plate 18 at a spaced distance above it,andthen turned rethe center of the rib 22, and having a jet nozzle 31removably engaged containing one or more perforations directed upwardly,there being a plug 32 removably engaged in the end of the burner headfor cleaning purposes.

A plurality of circular sheet metal discs 33, having radialcorrugations, are attached by friction band. 34: to the horizontalmember of the tube 27, one of said discs being disposed directly overthe nozzle 31 so that streams leading outward impinge on the disc and byit are directed outwardly around its entire circumference.

If it be necessary to clean any accumulation of sooty deposit from thedisc this mayv be easily and conveniently done by rotating the band 34so as to present a clean disc-to the flame, likewise rendering the sootydisc accessible for cleanin I have also found it desirable to make thesedeflector discs into a removable and readily attachable spreader unitsome embodiments of which are shown in Figures 5 to 9'. In Figures 5 and6, I have illustrated a spreader stamped of a single piece of materialand formed to provide parallel deflector discs 33 joined by therelatively narrow strip 40, the opposite side of the discs 33 beingprovided with tongues 41 pierced to provide a catch 4E1 for retainingthe arms 42 of the spreader unit in engagement with the tube 27; thearms 42 being also integral with their respective discs and bent atright angles to them to engage tube 27. The embodiment shown in Figure 7is in all general respects similar to Figures 5 and 6 except that threeinstead of two discs are provided from a single stamping. Obviously, ifthe catch 41 be opened the discs may be spread apart and thus removedfrom the tube 27. It is of great importance that these spreader units bemade of a single piece of material in order to avoid the use of rivetswhich arealways a source of much annoyance because of the readiness withwhich they collect soot and hold such accumulations against all effortsto cleanse thuslowering the efficlency' ofthe spreader discs.

While the preferred form of my spreader unit is stamped of a singlesheet of material, still I have shown two ei'nbodiments of removablespreader units in Figures 8 and 9 wherein the deflector discs 33ersriveted or otherwise fastened as at 43 to spring clamps 1 1 for easyattachment or removal from the tube 27.

I have shown the spreader discs in Figures 5, 6, 7, 8 and 9 as havingfiat surfaces but obviously they may be made with radial corrugations ifdesired, as shown in Figures 1, 2, 3 and 4;.

For some purposes it may be desirable to concentrate the heat from thechannel 20 in which case a perforate shield, as indicated at 37 inFigure 2, may be used, the same restmg upon ledges 15 on the innersurface of the walls 15, the walls of said shield convergingtowards theopen top, as shown.

23, which will direct oil spray to the wick recess. I

The flames from the wick and air entering the perforations 19 areintensely hot and following the walls 17, over the cap and along theraised rib 22 are concentrated to impinge upon the head 30 which actionsoon causes a pure to issue so that the same upon be ing ignited,strikes the disc 33 and is directed outwardly thereby,enough heathoweverbeing transmitted to the tube 27 to continue the process of gasmaking, draft being supplied from under the burner through theperforations 19 and openings 11 and 12.

In the initial operation, should an excess of oil enter the recess 20,it will be taken care of by the overflow pipe 35 set in a boss 36,formed on the bottom 16, and be delivered outwardly of the apparatus.

From the foregoing it will be apparent that one or more of the burnersmay be used as required; that the operation'is exceed- It is to beunderstood however, that the foregoing disclosure islargely descriptive,rather than limitive, and that minormodifications can be made asexperience dictates within the scope of the attached claims.
